WINDOW-CHAIR.

SPECIFICATION forming part of Letters Patent N o. 589,177, dated August 31, 1897. Application tiled May 12, 1897. Serial No. 636,181. (No model.)

To @ZZ whom t may concern: n

Be it known that' I, FRANTZ KAWEGKY, a

citizen of the United States, and a resident of` New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Vindow- Chairs, of-which the following is a specification.

This invention relates to a window-chai r of novel construction and designed to provide a safe and comfortable support for a person cleaning the window.

In the accompanying drawings, Figure l is a perspective view of my improved windowchair; Fig. 2, a vertical cross-section on line 2 2, Fig. l; Fig. 3, an inverted plan; Eig. 4, a detail of the rack-and-pinion mechanism; and Fig. 5, a section on line 5 5, Fig. 4.

The letter a represents the seat of my improved window-chair, to which are secured the depending side pieces b, terminating at their outer ends in short squared legs b,which are adapted to rest upon the window-sill.

Below the inner end of the seat a there are secured thereto by means of straps c the laterally-movable racks d, engaged at the center bya common pinion e. The outer end of each rack d is doubled or provided with a transverse arm d', and both the racks and the arms have upturned ends d2, surrounded by flexible buffers f. When the racks are by the revolution of the pinion moved laterally out- Ward, these buffers will tightly bind against the sides of the window-frame, so as to securely lock the chair in place without, however, scratching or otherwise injuring the window.

The arbor e of the pinion @passes through the central strap c and through a countersunk bearing-plate g of a reinforcing-strip d', which is secured below the inner edge of seat Ct. The upper end of the arbor e' is squared and is adapted to be engaged by a suitable key A, which may be passed through a keyhole-guard h, secured to the upper'side of structed'by one of the rack-teeth.

The operation of the window-chair will be readily understood. It is placed in position upon the sill,- the racks are moved outward by means of the key, so as to bear tightly against the sides of the window-frame, and then the bolt is inserted to lock the racks in their distended position. To remove the window-chair, the bolt'is withdrawn, when the racks will be released and may be pushed inward to become disengaged from the Window. A folding back and arm rest j, pivoted to the side pieces b, prevents the occupant of the chair from falling.

l. In a window-chair, the combination of a seat with a pair of laterally-movable racks having upturned ends, buffers secured to such ends, a pinion engaging the racks, and a bolt for locking the racks, substantially as specified.

2. In a window-chair, the combination of a seat with a pair of laterally-movable racks,

straps embracing the same, a pinion engaging the racks, a key-plate having a pair of bolt-holes, and a bolt adapted to engage either one of said holes and to lock the racks, substantially as specified Y.
